IMPROVEMENT IN SUBMARINE BOATS.

Specification forming part of Letters Patent N 0. 191,760, dated J une 12, 1877 application filed October 6, 1876.

To all whom it may concern:

Be it known that we, CHAS. F. HENIs and CHAS. F. PIKE, of Philadelphia, State of Pennsylvania, have invented a Submarine Car, of

of the covering removed from one arm, showing the metallic frame. The fall and flexible shaft (shown in Fig. 1) is omitted.

The shell of car a, Figs. 1 and 2, is made strong enough to resist the collapsingpressure of the water, and is provided with a manhole, I), Fig. 2, for entrance and exit. It is propelled by the propeller c, Fig. 1, which is driven by the engine d, Fig. 1. Direction is given to the car by the rudder c, Fig. 1, which is controlled by the' wheel f, Fig. 1. The air- .supply is forced into the space between the tubes 9 and h, Fig. 1. This space is closed at the point of connection with the car, forming an air-chamber. The tubes 9 and h, Fig. 1, have spirally-wound wire within thein, to pre' vent their collapsing. The tube h, Fig. 1, can be outside of the tube g, Fig. 1, if desired, making the air-space that much larger. Air for breathing is allowed to escape into the car through the pipe t, Fig. 1. The air to drive the engine is conveyed through the pipe j, Fig. 1. All exhaust-air passes up and out of the pipe h, Fig. 1. k, Fig. 1, is a speakingtube. 1 and n, Fig. 1, are wires, to connect a battery above with electric lights, for illumicomposed of wire wound spirally, but rings or plates similar to those used in ancient armor can be used.

The diver lies down, placing his head in the projection 0, and his arms in the flexible arms 1; giving them free motion to grasp any substance. In case of greater weight than one can lift, his companion assists by operating the fall s, Fig. 1, through the arms 1) p.

A buoy or float can be connected to the eyebolt t, Fig. 1, to prevent tilting, if desired. His companion also controls the propelling and steering of the car, and regulates the motion of the shaft u, Fig. 1, on the end of which is attached the shaft 3), Fig. l, which can be either flexible or constructed with toggle-joints which can be placed in any position while in motion, operating any tool required. The rotary motion can be converted into a reciprocal, if necessary.

The adjustable legs to w w w, Figs. 1' and 2, are attached to the outside of the car, and are operated on the inside by the levers w .12, Fig. 1, like a hydraulic jack. In case it is necessary to throw the bow down, to enable the diver to work to better advantage, the bowlegs are drawn up and the stern-legs forced out. To elevate the how, the operation is reversed.

On the outside of the car are the compartments 3 y, Fig. 2, which are filled with water to sink, or air to float, the car, as may be desired. To fill the compartments with water, open the valve 2, Fig. l, which leads into the car, and the water will fill the compartment. When full, close the valve z. To fill the compartment with air. open the valve a, Fig. 1, in the pipe b, Fig. 1, which connects with the air-chamber. The air, being at a higher pressure than the water, will force the water out and occupy its place. Close the valve a when the compartment is full. 0 is a valve, leading out of the compartment into the water, to be closed in case of necessity. The'amount of water or air can be regulated as desired.

d and c, Fig. 1, are supply and exhaust pipes, to be used for operating a drill or other mechanism, or to fill floats outside of the car.

N 0 claim is made for the body of the car, as various-shaped cars have been made.

What we claim is g, in combination with the car, substantially as and for the purpose set forth.

5. The combination of the tube 9 with the spirally-wound wire, substantially as shown and described.

6. The tubes at and e, in combination with the ear, substantially as and for the purpose set forth.
